Mikaela Mayer is undefeated in 16 fights and holds two world titles

I was always meant to do something big, even if she wasn't sure how it was going to be.

She was in a heavy metal band when she was a teenager. Her future seemed to be in music.

Before boxing, I had my nose pierced, my tongue was pierced, my ears were pierced, and my hair was black. Nita was my singer and guitarist. She is the lead guitarist for Alice Cooper.

It was his nature to give or not. She quit that band when she had enough.

I had a stage where I was just out partying, being a bad kid, and driving my dad crazy so he wouldn't come home for weeks at a time. She recalls that she came back around and said that she needed to refocus herself.

She went to the gym. She was smoking a pack of cigarettes a day when she first arrived at the gym, but within a week she could no longer do it. I want to be the best female fighter in the world.

I guess you have to be a little crazy to have dreams like this. I told my dad that I was doing something positive and that he was fully supportive.

She would box for the USA at the Olympics. She hadn't been sure where to go after that tournament.

I knew I was done with them. I was going to MMA because women were getting the TV time, the contracts, and I didn't know where to go from there.

It was time for me to challenge myself somewhere else and I was willing to get kicked in the head to do that.

She signed with US promotional powerhouse Top Rank. She is a world champion in the super-featherweight division and has won 16 pro fights.

In her last fight, she issued a statement of intent. She turned her November unification against Maiva into an intense battle from the first bell. It was one of the best fights of the year.

After the first round, I knew I was going to bang with her more than I was going to box.

In California on Saturday, Mayer will attempt to retain those titles. The American challenger will be a clear favorite but has previously gone the distance with Taylor.

It was a tougher fight than Taylor thought and it will give people a chance to compare me. To see where I am at. I won't bang it out like I did with Hamadouche.

She says that no fight is an easy fight. Being a female in this era of boxing for women, when we are trying to grow the sport and try to close the gap of equality and get the respect that we deserve, he wants me to look good. He doesn't want me to coast by and win. He wants me to look good.

If she succeeds against Han, she will look to challenge the winner of Taylor's fight with Serrano at the end of April.

I would love that. I wanted to go undisputed at 130 lbs, but I am not going to sit around and not try and take the biggest fights I can in the meantime.

They both have different styles and different background. I'm not sure if it's because she's been a pro for five years or because she's an amateur. A good one, a great one, it worked for her.

Serrano is the opposite. She has a sound that is very professional. It will be a battle of styles. We will see who has the better gameplan, more disciplined throughout the 10 rounds.

He would be happy to fight.

She says she wants to see herself on the top of that pound-for-pound list. I will leave the sport knowing that I challenged the best.

I am willing to leave it all on the line.
